+# Use your own registry in Minikube
+
+For development needs you may enable local docker registry.
+
+## Configuration
+
+Start node and enable registry addon
+
+	$ minikube start
+	$ minikube addons enable registry
+
+You should see registry pods and services:
+
+	$ kubectl get pods --all-namespaces | grep regist
+	kube-system            registry-proxy-46f6z                         1/1     Running   1          7h38m
+	kube-system            registry-qdlgr                               1/1     Running   1          7h38m
+
+	$ kubectl get service -n kube-system | grep regist
+	kube-system            registry                    ClusterIP   10.96.159.133   <none>        80/TCP                   7h38m
+
+Add registry DNS records to `/etc/hosts` files:
+
+	$ REGISTRY_IP=$(kubectl -n kube-system get svc/registry -o=template={{.spec.clusterIP}})
+	$ echo $REGISTRY_IP
+	10.96.159.133
+	$ minikube ssh -- "echo -e '$REGISTRY_IP\tregistry.kube-system.svc.cluster.local' | sudo tee -a /etc/hosts"
+	$ minikube ssh -- cat /etc/hosts
+	127.0.0.1	localhost
+	127.0.1.1	minikube
+	10.96.159.133	registry.kube-system.svc.cluster.local
+	$ kubectl apply -f https://k8s.io/examples/admin/dns/dnsutils.yaml
+	$ kubectl exec -ti dnsutils -- nslookup registry.kube-system.svc.cluster.local
+	Server:		10.96.0.10
+	Address:	10.96.0.10#53
+
+	Name:	registry.kube-system.svc.cluster.local
+	Address: 10.96.159.133
+
+	$ echo -e "127.0.0.1\tregistry.kube-system.svc.cluster.local" | sudo tee -a /etc/hosts
+	10.96.159.133	registry.kube-system.svc.cluster.local
+
+Forward registry to localhost:
+
+	$ kubectl port-forward --namespace kube-system service/registry 5000:80 &
+	$ curl registry.kube-system.svc.cluster.local:5000/v2/_catalog
+	{"repositories":[]}
+
+Tag and upload image to your registry
+
+	$ docker tag devel/myapp:v1 localhost:5000/devel/myapp:v1
+	$ docker push localhost:5000/devel/myapp:v1
+	$ curl registry.kube-system.svc.cluster.local:5000/v2/_catalog
+	{"repositories":["devel/myapp"]}
+
+## Using
+
+Write manifest:
+
+	$ vim myapp.yaml
+	apiVersion: v1
+	kind: Pod
+	metadata:
+	  name: myapp
+	  labels:
+	    app: myapp
+	spec:
+	  restartPolicy: Never
+	  containers:
+	  - name: waiter
+	    image: localhost:5000/devel/myapp:v1
+	    command: ["/bin/sleep","120"]
+
+Apply it:
+
+	$ kubectl apply -f myapp.yaml
+
+Watch pod activity:
+
+	$ kubectl get events --field-selector involvedObject.name=myapp
+	LAST SEEN   TYPE     REASON      OBJECT      MESSAGE
+	<unknown>   Normal   Scheduled   pod/myapp   Successfully assigned default/myapp to minikube
